POWER SOURCE CONNECTION
On the rear panel is a small (2.1
mm)
coaxial
jack;
the
inner
conductor has PLUS and the outside
MI N US
p o la ri ty .
C o nn e ct
the
supplied cable to a regulated 12 to
14 Volt power source and pay
attention that the red wire goes to
the POSITIVE (+) pole and the blue
to the MINUS (-) pole.
The utilization of modern CMOS
semiconductors results in a low
power consumption of only 0.5 A.
The decoder requires a stabilized
voltage source. WAVECOM recommends
the use of a somewhat larger than
necessary supply, if possible,
about 2 to 3 Ampere output.
The W 4010 decoder has an internal
fuse that protects not only against
overcurrent, but also against wrong
polarity.
1.2
RECEIVER CONNECTION
The W 4010 demodulator needs audio
from the receiver with a level of
about 0.1 Vpp, up to a maximum of 5
Vpp. Many receivers have line or
tape recorder outputs which have
fixed levels, and it is recommended
to use these because their outputs
are independent from the volume
control. The large AGC range of the
decoder permits using it with
almost any receiver.
For the connection to the receiver,
use the supplied cable which is
shielded and has RCA plugs on both
sides. An adapter will have to be
used for 2.5 or 3.5 mm coaxial
receiver jacks.
1.3
VIDEO MONITOR INTERFACE
Use the supplied RCA-RCA shielded
cable to connect the video output
to the 75 Ohm input of the
composite video monitor. The video
card has a 75 Ohm terminated output
of 1.5 Vpp which can be used by all
commonly available monitors.
A
modulated
TV
output
is
deliberately not available, since
TVs do not have the necessary
bandwidth to give sharp and clear
text.
1.4
VIDEO DISPLAY SELECTION
Choose module A by pushing the
module key while watching the
monitor. Thereafter push F1 to
obtain the menu to setup the
parameters. The F1 key allows
configuring the video 40 characters
x 18 lines or 80 characters x 24
lines.
The cursor mode can be adjusted
with F2: no cursor, cursor no
blinking, cursor slow blinking,
cursor fast blinking.
The video synch frequency can be
adjusted with F3 to 50 Hz or 60 Hz.
Page 3
In case of unreadable video text
switch the W 4010 Off, switch On,
push F1 and then F3.
The programmed values are stored in
a non-volatile memory and keep
stored even without power.
1.5
PRINTER
INTERFACE
PARALLEL
Before interconnecting the printer
with the W 4010, make sure both
units are turned off. The 36-pole
Centronics printer output jack is
located on the decoder's rear panel
and
is
connected
via
the
standardized Centronics cable to
the similar jack on the printer.
The printer can be used immediately
thereafter. Although the Centronics
printer
signals
have
been
internally filtered against RFI
emissions, it is recommended to use
shielded cables only.
Some services use high Baud rates
with the result that not all
printers can keep pace. Before
buying a printer, make sure it can
print as fast as the service which
you wish to receive, otherwise
characters will be lost when the
buffer is full.
The RS-232 serial connector is the
5 pole DIN type and the diagrams
below
show
the
electrical
connections and give a typical
connection example. Shielded cable
is recommended, although it is not
absolutely necessary.
The baud rate and data format of
the equipment connected to the
serial port and the WAVECOM decoder
has to be identical. The serial
port parameters for the decoder
default to 300 baud, 8 data bits,
and 1 stop bit. The decoder offers
the possibility of inverting the
data shift, should this eventually
be
necessary.
To
invert
the
polarity, open the case and change
the position of the jumper, right
front, towards the front panel.
5-pole serial connector, DIN type:
1.6 SERIAL RS-232 INTERFACE
The DTR line signals the decoder
whenever the printer cannot accept
any more characters. If this handshaking is not necessary in a
particular case, this connection
does not have to be made. Xon/Xoff
handshaking is not supported.

that from the serial port except
that this output has a level of 0

FORMAT
FOR
SERIAL COMMINICATION
Choose module A by pushing the
module key while watching the
monitor. Thereafter push F2 to
obtain the menu to setup the
communication parameters. The F1
key allows configuring the Baud
rate to either 300, 600, 1200,
2400, 4800, or 9600 Baud
The parity can be adjusted with
help of F3 to NO, ODD, or EVEN.
The programmed values are stored in
a non-volatile memory and stay
stored even without power. By means
of F1, F2, and F3 the operator can
easily
configure
the
WAVECOM
decoder to communicate with any RS232 equipment.
The number of data and stop bits
can be adjusted with F2 to either 7
level signals.
In order to transfer the data's of
the
serial
interface,
it
is
necessary
to
load
a
terminal
Program in a PC. With the terminal
Program you can save the data's on
a disk.
1.9 HOW TO INSTALL THE SOFTWARE MODULES
Before undertaking any changes in
the equipment make sure the power
is disconnected.
1.8 USING AN EXTERNAL
DEMODULATOR
The EPROM memory chips have an
easily seen indentation on one end.
When inserting the EPROM, this
indentation must point to the front
of the equipment. Also the EPROM
markings should be oriented similar
to that of EPROM A. The EPROM has
to be inserted in the proper sense,
otherwise it probably will be
destroyed!
Set the DIP switch, located behind
module C, as follows:
In order to connect an external
demodulator you must first open the
case. Locate jumper #3 and change
it from the left-hand position
(internal
demodulator)
to
the
right-hand position (seen from the
front
panel).
The
external
demodulator can now be connected to
the 5-pole DIN rear panel jack. The
external demodulator input can be
driven with either TTL or RS-232

FILTER
CONTROL
The model W 4010 has a continuously
variable bandpass filter which is
independent of the baud rate or
shift thereby allowing optimal
signal
filtering.
This
filter
offers
the
operator
many
advantages.
The variable-width bandpass filter
is similar to the quartz filter
used
in
shortwave
receivers.
However, the W 4010 variable-width
bandpass filter differs in two
ways:
1.
The
bandwidth
is
fully
adjustable from 10 Hz to 2300 Hz.
The advantage is that the bandwidth
can be optimally adjusted for all
received shifts.
2. The W 4010 bandpass filter has
an attenuation of over 27 dB when
the input frequency exceeds the
filter corner frequencies by more
than 200 Hz. This filter response
is an optimum compromise between
unwanted
signal
attention
and
intersymbol distortion caused by
filter group delay. The reason for
this is that very strong signals
cause the receiver AGC to reduce
the strength of the desired signal
to that of the noise.
When
receiving
a
strong
and
interference-free
signal,
this
filter is not necessary and the
adjustment knob can be turned fully
counter-clockwise to disable it.
During reception of very strong
signals, turning the knob to the
right has little effect because the
signal is stronger than the filter
attenuation.
There
is
no
disadvantage to this since the
filter is not necessary for strong,
interference-free signals.
In case there is interference from
a nearby station, the knob can be
turned clockwise until the point is
found where the interference is
nulled out and at the same time the
LED shift indicator shows a wide,
clean
shift.
W ith
a
l ittl e
practice, the optimum point can be
found quickly. Reception fails only
when the shortwave receiver has
become overloaded. At this point
the only remedy is a good crystal
filter in the receiver; an audio
filter
is
not
a
cure
for
overloading in the HF receiver
stage .
A
cr ystal
fil ter
is
es p ec i all y
i mp or ta n t
f or
CW
reception since interference is
often closer in frequency than 200
Hz. Depending on the quantity of
si g na l s
w ith in
t he
r e ce i ve r
bandwidth, adjust the audio filter
bandwidth for optimum results.
2.4
LEVEL CONTROL
The Model W 4010 has a continuously
adjustable squelch circuit which
acts upon the signal amplitude:
when a signal is below the preset
level ,
it
is
squel ched
out
completely. Above this level it
passes through the squelch with no
attenuation. This is especially
important
for
CW
because
the
squel ch
c an
be
adjus ted
in
accordance with the interference
level. In fact, the squelch is
necessary to prevent interference
from reaching the decoder circuitry
during morse pauses, which would of
course cause characters to be
falsely decoded.
The squelch works in the modes CW,
ARQ, and packet-radio, but in all
other modes the knob has no effect.
The squelch has no effect when the
knob is turned fully counterclockwise, whereas when turned
fully clockwise the squelch effect
is the strongest.
In ARQ and packet-radio modes the
squelch causes the LED display to
center itself during the pauses and
makes tuning of these narrow-shift
modes much easier.
2.5
BAR-GRAPH DISPLAY
Find a RTTY signal and turn the
filter
knob
counter-clockwise
(filter disabled) and adjust the
frequency of the receiver so that
flickering LEDs move towards the
outside and are symmetrical to the
middle. With a shift of 170 Hz the
outmost LEDs should light up, but
with a shift of less than 170 Hz
the
inner
LEDS
will
indicate
maximum deviation.
Page 7
With F7-B signals look for the two
inner
tones.
These
can
be
recognized by the two LEDs with
somewhat brighter intensity. Tune
the receiver so that these two
inner tones are symmetrical to the
middle. Remember that F7-B (F6)
signals
do
not
tolerate
much
mistuning since the tones are only
100 Hz apart. The receiver must
have a high frequency stability and
should have the ability to tune in
fine steps of about 10 Hz.
With morse signals there is only
one tone and with no signal the LED
display moves to the right. CW
keying should move the display past
the middle over to the left-hand
side. The frequency for CW is the
more or less standard 800 Hz, which
sounds
rather
low.
With
interference, adjust the minimumamplitude squelch such that the
display is moved only by the CW
tone. Also the audio filter can be
adjusted to the narrowest bandwidth
as necessary.
The transmission of a weather-chart
has a typical noise, a noise which
one soon learns to recognize. The
transmission is accompanied by a
certain movement of the tuning
display. Most stations work with a
broad-band shift of +/- 400 Hz.
which causes a larger movement of
the display, but a few stations use
a narrow-band shift of +/- 150 Hz
with resulting smaller display
movement.

IOC,
but
also
when
a
chart
transmission starts and when it
ends. This information is conveyed
by a series of control tones before
and after a chart transmission.
WEATHER CHART TRANSMISSION SYSTEM
Weather charts can be transmitted
by radio by fixing them to a
rotating drum. A light sensor which
moves slowly along the length
co n ve r tin g

i nt e ns i ty
of
reflections into voltages. These
voltages are converted into tones
which
can
be
transmitted,
respectively received.
On the transmit side, the speed of
drum rotation is called RPM and the
speed at which the sensor moves
along the length of the drum is
called Index of Cooperation (IOC).
On the receive side, it is not only
necessary to know the RPM and the
The first tone in the series is a
signal of 300 or 675 Hz and gives
the IOC value. This tone continues
for 5 - 10 seconds and can be used
to accurately tune in the receiver.
Following this, the frequencies
representing black and white are
transmitted alternatively at a rate
of 1 - 2 Hz for a period lasting 30
seconds. This part of the tone
series conveys the RPM and allows
the
receiving
station
to
synchronize permitting the image to
be printed in the middle of the
paper.
Page 8
Afterwards the transmission of the
weather
chart
commences.
The
received output can be printed on a
graphics-capable printer via the
CENTRONICS parallel print port.
Both 9-pin and 24-pin printer can
be used in A4 portrait mode. Since
weather pictures are continually
printed,
the
printer
must
be
capable of printing 150 characters
per minute.
After the end of the picture, the
stop signal is sent. This consists
of an 450 Hz tone with a length of
5 seconds, followed by the tone
frequency representing black which
lasts 10 seconds.
The new Remote Control of the W
4010 enables the communication
between the decoder and a computer
(PC/AT)
via
a
serial
RS232interface. The commands sent by the
computer to the decoder will be
interpreted inside the W 4010 and
transposed into the equivalent unit
settings.
The configuration of the serial W
4010
Remote
Control-interface
always has to suit to the settings
of the PC. To that belong the baud
rate, number of data- and stoppbit
and the parity. The configuration
of the W 4010 interface happens in
a special mode via the keys at the
front panel. The data are kept in a
nonfluent memory (EEPROM)and even
stay after a power lack.
The PC additionally can receive
teletype
data
via
the
RS232interface, exhibite them on the
monitor and save in a file.

The operation of the decoder via
the keys is also possible during
the remote operation. The software
registrates the manual settings.
The changed parameters can be asked
via the interface and be evaluated
by the PC.
But the user can also write his own
software or even can steer the W
4010 from the WINDOWS terminal
program.
The configuration menu becomes
activated by pressing the key MODUL

The data links will, like specified
by JV-FAX, be switched to the W
4010 demodulator. With this, the W
4010 can be used as a demodulator
for black-white faxpictures. The
command JV-FAX must only be given
in DOS, due to the switching of the
data lines.
The communication between PC and
the W 4010 occures by a firm set of
commands and answers. The content
of all commands will be transmitted
in ASCII.

After the equipment is turned-on,
EPROM A is enabled. The video
display now tells you that the
possibility exists to set the
parameters for the serial port,
video interface or weather-fax
setup. The key F4 must be used to
choose ARQ-FEC.
Turn both knobs, filter and level,
fully counter-clockwise and look
for an ARQ signal. The level
adjustment serves as a tuning help
because with it the tuning display
goes to the center during block
pauses and the frequency deviation
can be seen clearly. After tuning
has
been
finished,
it
is
recommended to return the level
adjustment to its neutral position
to enable the reception of very
weak
ARQ
signals.
The
level
adjustment is not needed with FEC
signals and is therefore switched
off for this mode. Nearby undesired
signals can be nulled out with the
filter; it can easily be seen on
the tuning display when the filter

is optimally adjusted. Narrowing
the filter bandwidth is always an
advanand FEC signals. If this is
not desired, then one of these
modes can be selected. LSB or USB

The BU-ZI key switches between RTTY
letters/numbers should this happen
to be false. The switch causes no
signal interruption, but is only
effective when a signal is actually
being received. The optimum FEC
software
is
also

Sitor is a simplex ARQ system where
both stations alternately send on
the same frequency. The CCIR Rec.
476-4 defines a period of 450 ms
and the two stations are called:

signal.
In

ISS
IRS
The Baud rate is always 100 Baud, i.e. 10 ms bit length.
The ISS sends 210 ms blocks of 21 bits.
The IRS sends 70 ms acknowledgement pulses.
The two IRS acknowledgement pulses, called CS1 + CS2, confirm
error-free
reception; the repetition of the same control character tells the ISS
to repeat the last block, respectively the last 3 characters.
If the ISS does not receive an acknowledgement, it sends an RQ block.

Each character is sent twice with

error-free characters reach the
output. If both characters have
errors then the special character

the adjustment of the level knob

critical
and
difficult. Each operator should

CW signals can be decoded errorfree even with strong interference.
The Morse code is one of the oldest

through
these
3
possibilities, the monitor mode is
selected again where all packets
are received. Whenever the packetradio mode is chosen, the stored
call signs are deleted. Until

has no function.
The call sign of the selected
station appears in the command
line, and only packets that have
this call sign will reach the

originator, recipient, or possible

possible to monitor all activity of
a certain station or repeater.
With packet radio many stations can

A large number of stations around
the word transmit weather charts at
certain times. To print a picture
it is important that the printer
has paper in it and is in the
status ON LINE. Additionally the W
4010 push button PRINT will have to
be pushed (the LED PRINT MUST
glow).
If it is desired to print the next
picture, leave the W 4010 in the
AUTO MODE, which is the default
mode after turn on. A weather
picture needs 10 - 40 minutes and
when the next picture starts, the
LED TRAFFIC will glow as the
picture is being printed.
If it is desired to receive a chart
transmission
that
has
already
started,
choose
an
IOC
value
(usually 576) as well as a drum
speed. Thereafter push the F1 key.
A scale will first be printed and
this can be used to correctly
position the picture by using the
PHASE key. In case the picture
image is in negative (i.e. white on
black), choose the other sideband
and tune in again. Weather FAX
transmissions are sent in upper
sideband (USB or FAX). Before
transmission is started, the key
BU-ZI
can
be used
to
enable
reception on LSB. When the picture
is finished printing, the W 4010
sends form feed to the printer
after
prints
the
information
"WAVECOM W 4010 WEATHER-FAX" on a
row.
AUTO: The F1 key is used to switch
between automatic and manual chart
reception.
If
switched
to
automatic, the W 4010 chooses the
correct values for IOC and RPM as
well as starting a print-out of the
synchronization signal, the TRAFFIC
LED glows; the SYNCH LED glows when
the transmission begins.
MANUAL: This mode starts the printout by hand. For a short time, both
SYNCH

glow,
thereafter only the traffic LED
glows. The values of IOC and RPM
must, however, be manually set
beforehand. If the key F1 ist

DRUM SPEED: Used to adjust the drum
speed RPM during reception by
choosing 60, 90 or 120 RPM. The
chosen speed appears in the status
line.
IOC MODUL: Used to adjust the Index
of Cooperation (in German: MODUL)
to either 288 or 576; the selected
IOC being displayed in the status
line. The IOC must be chosen before
the synchronizing tones of 300 &
675 Hz. An IOC of 576 is by far the
most commonly used value.
POLARITY POS-NEG: The key BU-ZI
selects either positive or negative
image polarity, the selected value
being displayed in the status line.
Negative polarity offers advantages
for the reception of satellite
pictures.
PHASE LEFT / PHASE RIGHT: When the
print-out is started by hand the
converter has not received the
synchronization at the start of the
transmission. In this case it is
easily possible that the picture is
not in the middle of the paper.
After manually starting, the W 4010
prints out a scale across the
entire width of the paper.

Use these keys to position the
picture correctly. For example,
when the left margin of the picture
is under the symbol <<5, push the
keys F1+F2 five times. The selected
value is displayed in the status
line. The reaction of the printer
is delayed, however, with the delay
detirmined by size of the printer
buffer.
FINE SPEED UP / FINE SPEED DOWN:
The
FAX
picture
is
only
synchronized at the begining of
transmission. If there is a small
difference in drum speed and the W
4010, the picture will start to
drift in one direction or the
other. These fine speed (FS) keys
can be used to compensate and
correct this difference.

The software preselects 96 Baud for

used to manually change the Baud

block repetition (RQ) cycles are
initiated.
The software uses 125 Baud as a
default since this is the most
common speed, but the F2 key can be
used to change the speed. The
polarity (sideband) is changed with
the F3 key and causes no loss of

H owever,
in

condition it is neither possible to

Every second bit is used for error
correction
and
the
characters
consist of 14 bits. The errorcorrecting code not only corrects
single errors, but also error
bursts, in fact error bursts of up
to 1 second can be corrected.
This

system uses the same alphabet as
the single-channel ARQ system.

ARQ CCITT-3 sounds very similar to
Amtor-Sitor, except one has the
impression of a slower Baud rate
due to the longer blocks for
characters and pauses. The standard
speed is 96 Baud and the block
length
is
usually
5
or
6
characters. A Baud rate measurement
is very difficult because there is
no signal between the character
blocks.
Therefore,

Transmitted block can have a length
of 4, 5 or 6 characters. A cycle is
twice as long as the block length.
If the ISS receives the
acknowledgement, then the next
block is transmitted with opposite
phase. The transmission rate can be
chosen from among several Baud
rates. The Wavecom software always
receives the ISS (Information
Sending Station).
The timing of the 2 stations looks like:

Remove the two screws on each side
of the case and then remove the top
and bottom covers. The fuse holder
is located on the right-hand side
of the PCB near the rear, and the
fuse can be pulled easily from the
holder. Use only a small fuse of 5
x 20 mm dimensions with maximum 2
A, rated as fast-blowing.
If,
after
first
checking
the
correct polarity of the supply
voltage, the fuse blows again, the
problem is in the equipment. Never
replace the fuse with one of higher
rating or with an aluminum foil
short, since this will damage the
equipment further.
All microprocessors and various
peripherals can generate broad-band
radio-frequency interference (RFI),
which may be radiated by the
interconnecting cables. The WAVECOM
equipment is engineered to reduce
this RFI to a minimum by utilizing
RF chokes on all outputs. A metal
case
is
used
to
shield
the
circuitry, and as a further RFIpreventing measure, each PCB is
individually shielded with copper
foil. Video monitors and printers
also
can
ca use
stron g
RFI.
Therefore,
the
following
precautions can be taken concerning
the receiver installation:
susceptible to interference if this
is not the case. An antenna tuner
(so-called match box) can be used
to transform the antenna impedance
to 50 Ohms.
Antenna:
A poorly installed antenna or
receiver feedline is one cause of
interference.
Interference
is
seldom present when a long-wire
antenna, installed in the clear,
together with shielded cable are
used. However, if a simple active
antenna is used in the neighborhood
of
the
deco der
or
monitor,
interference
can
be
expected,
especially at higher frequencies.
In general, active antennas are
more susceptible to interference.
Receiver:
Often RFI is radiated directly into
the receiver because it does not
have sufficient shielding. Many
receivers need a 50 Ohm load on the
anten na
i nput
and
ar e
very
HF cabling:
All the antenna lines inside a
house should be run with shielded
HF cable.
AC line interference:
Often video monitors and other
electronic equipment radiate into
the AC line and enter the receiver
or active antenna via their power
supplies. This type of interference
can be reduced by means of an AC
line filter.
Ground:
The best ground is the cold water
metal pipe as the hot water pipe is
not
always
grounded.
A
good
receiver
ground
is
always
recommended, not in the least for
your own safety.
Placement of the decoder:
Despite
the
decoder's
double
shielding, it is still possible
that interference persists in the
near vicinity of the receiver. It
helps in this case to change the
location
of
the
decoder
with
respect
to
the
receiver.
Interference from video monitors
can often be remedied only by using
this method.

The new Remote Control of the W
4010 enables the communication
between
the
decoder
and
a
computer (PC/AT) via a serial
RS232-interface. The commands
sent by the computer to the
decoder
will
be
interpreted
inside
the
W

and
transposed into the equivalent
unit settings.
terminal program.
can receive
the RS232them on the
a file.
The configuration of the serial
W 4010 Remote Control-interface
always has to suit to the
settings of the PC. To that
belong the baudrate, number of
data- and stoppbit and the
parity. The configuration of
the W 4010 interface happens in
a special mode via the keys at
the front panel. The data are
kept in a nonfluent memory
(EEPROM)and even stay after a
power lack.
The well-known PC-program RADIO
MANAGER for WINDOWS
of
the
company
SHOC
supports
all
functions
automatically.
The
RADIO MANAGER can now remote
receiver
and
decoder,
what
before only was possible with
the professional W 4100.
The configuration menu becomes
activated by pressing the key
MODUL when the W 4010 is being
switched
on.
The
setting
possibilities are shown selfexplaining on the monitor. To
leave this mode, the decoder is
simply switched off.
The operation of the decoder
via the keys is also possible
during the remote operation.
The software registrates the
manual settings. The changed
parameters can be asked via the
interface and be evaluated by
the PC.
Additionally
to
the
known
teletype-modes,the W 4010 knows
the switching to the new mode
JV-FAX. The data links will,
like specified by JV-FAX, be
switched
to
the
W
4010
demodulator. With this, the W
4010
can
be
used
as
a
demodulator
for
black-white
faxpictures. The command JV-FAX
must only be given in DOS, due
to the switching of the data

The configuration of the serial
RS232
interface
and
the
presetting of the unit`s address
can
be
effected
at
the
configuration menu.
The software of the W 4010 does
not answer with an echo sign to
the host. When operating with
the terminal program (on a PC)
the
terminal
should
be
configured at AUTO—ECHO.
After the receipt of the string
“PORTxx=ON<CR>“
the
W
4010
switched to mode REMOTE. The
expression “xx“ stands für the
unit`s address from “0“ to “15“.
All the keys are in function
furtheron.
The
W
4010
registrates all manual inputs.
After the receipt of the string
“PORTxx=OFF<CR>“ the W 4010 does
not
answer
any
more.
The
software
only
answers
to
commmands after the receipt of
the command PORTxx=ON. So it is
possible to use several units at
the same RS232 interface or to
use the PC-interface itself for
several times.
Each command string from the PC
to
the
W
4010
has
to
be
acknow ledg ed
by
‘C arri ag e
Return’.
The ‘Carriage Return’
is shown as <CR> in the above
example. The W 4010 works the
sign string down, executes the
necessary actions and answers
with a “>“ at the PC (the
apostrophes
do
not
get
transmitted).
If the command is not defined or
there is an error in it, the W
4010 transmits the sign ‘?>’.
The software works with capital
and/or short letter.
By adding a question-mark at the
end of a command the PC can ask
all settings from the W 4010.
The
W
4010
transmits
the
corresponding setting to the PC
after
the
questioning,
respectively finished by <CR>
and the last sign ‘>’.

The command “DATA“ steers the output of the received teletype data
from the decoder over the remote interface to the PC.
At the command “DATA“ following has to be noticed:
- after transmission of the command “PORTxx=OFF“, also the output
of the data stopps.
- when switching between “PORTxx=OFF“ to “PORTxx=ON“ the output of
the data continues, if “DATA=ON“ if "DATA=ON" was setted before.

HINTS:
• The
switching to JV-FAX must only happen in DOS. The W 4010
switches the necessary lines for JV-FAX on the demodulator. This
switching of the RS232-steering lines leeds to disturbances in
WINDOWS.
• The voltage range of the A/D-converter can be adapted to other

First the four screws of the upper case lid have to be removed. Upper and lower lid can be put
aside.
Then the back panel has to be removed. Therefore first the voltage regulator has to be screwed off (see
page 5). When this has happened, the four screws of the back side get screwed off and the panel can be
taken away.
Now in opposite succession the back panel can be rearranged again.
Put the W 4010 with the front to you.
